The Flaming Lips are Oklahoma's most famous art rockers and have been making music that both challenges and inspires for nearly a quarter century. Their latest CD is a mix of multi-layered psychedlia and spacey rock.

Ambulance LTD is a New York rock group. On their new EP they offer a few new tracks and one beautifully constructed cover of Pink Floyd's "Fearless," a song that originally appeared on the 1971 LP Meddle. Known for its exhaustive and inspired collections of hard-to-find music, the Smithsonian Folkways label compiles classic railroad songs for its latest collection. The work songs and ballads inspired crews as they laid tracks from coast to coast. Furry Lewis is one of several artists featured on these vintage recordings.
